Serotypes of previously unclassified isolates of Erysipelothrix rhusiopathiae from swine in the United States and Puerto Rico.
Serotypes of 46 previously unclassified isolates of Erysipelothrix rhusiopathiae from porcine tissues in the United States and serotypes of 31 isolates of the organism from porcine tissues received from Puerto Rico were determined. The 46 isolates from the United States were classified in serotype 21. Four isolates (from Georgia, Minnesota, Ohio, and Oklahoma) were tested and found to be pathogenic for swine. Serotypes 1 (subtypes 1a and 1b), 2, 5, 6, and 21 were found in porcine tissues from Puerto Rico. The relative frequency of the various serotypes was similar to that previously reported in the United States.
